In the second year of Shunzhi (1645), Wu Da and others impeached Quanfeng to accept bribes from Ming generals and connived at their children's evil deeds. In August, Li Senxian pointed out: "The world in the Ming Dynasty was not as good as that in Wei Zhongxian for more than 200 years, and Wei Zhongxian killed the virtuous ministers, paid bribes and plotted against Quanfeng at that time. Request to abandon Quanfeng and enter the city to show Dafa. " Li Senxian's this play hydrophobic, text is extremely cold, sensation in one's hand. Later, due to the up-and-down activities of Quanfeng, when the Qing Dynasty employed people, the matter went away, but Li Senxian was dismissed and returned to his hometown.
In December of the ninth year of Shunzhi (1652), all ministers convicted of impeaching Quanfeng were appointed, and Li Senxian was reinstated.
In the 13th year of Shunzhi (1656), Li Senxian inspected the south of the Yangtze River under the supervision of Sichuan Road. At that time, the anti-Qing struggle in Jiangnan had vanished, but the society was extremely chaotic. Local ruffians and hooligans are rampant, and the gentry bully the people, which has seriously affected the stability and development of Jiangnan. There are also some new local officials who regard Jiangnan as a land of wealth and corruption at will, further aggravating the social unrest in Jiangnan. After Li Sen first arrived in Jiangnan, he quickly curbed these ethos and stabilized the order in Jiangnan.
In the 15th year of Shunzhi (1658), Li Senxian asked the imperial court to speak out and pardon Li Chengxiang and others who were convicted for their words. At the request of the imperial edict, he roughly said: "The emperor has been tirelessly seeking the balance of the world and has repeatedly requested the imperial edict, but many ministers hesitated to wait and see, because once the ministers who used to write were punished, they would be exiled forever. They all took this as a warning and warned each other. I think that if you want to speak freely, you should be tolerant of the ministers who make suggestions. Such as Li Chengxiang, Ji Kaisheng, Wei Yi, Li Yi, Hao Yu, Zhang Mingjun and other exiled admonishers, are all related to the next imperial edict allowing admonishers because of their official positions. If you suffer from the emperor's concern and pity, let the whole world know clearly that the emperor is tolerant of the immediate ministers, and even if they are sent to remote places, they will not be left out. Anyone who has the responsibility to make suggestions and suggestions can make suggestions and suggestions without washing their minds? " The emperor accused him of bending the law, deprived him of his official position, appointed punishments to discuss crimes, and exiled him to Shangyangbao. Three months later, the emperor shunzhi pitied his loyalty, pardoned him, reinstated him, and ordered him to investigate the famine in Henan. When Li Sen first arrived in Ruzhou, his integrity and extraordinary talent quickly won the favor of the local people.
At that time, farmers in Ruzhou reclaimed land, because the bow used to measure the land was not standard, and fights and lawsuits often occurred. Knowing this situation, Li Senxian ordered the unified measuring bow and carved the standard length on the stone tablet, which fundamentally put an end to the controversy. It has promoted the development of land reclamation. Due to overwork, Li Sen fell ill a few months after arriving in Ruzhou, and died in the seventeenth year of Shunzhi (1660).
